## About

Stratoscale was founded in 2013 by Ariel Maislos, a serial entrepreneur who previously founded Anobit Technologies, an enterprise flash-storage company acquired by Apple in 2011. The founding team, based in Sunnyvale and backed by an Israeli R&D center in Herzliya, set out to commoditize the cloud control plane. Their thesis — now validated by the market — was that enterprises wanted public-cloud programmability without surrendering hardware control to a single vendor. The company's core product, Symphony, functioned as a drop-in AWS Region. It translated the S3, EC2, and VPC API sets into a software-defined data center layer that ran on x86 servers. This allowed banks, defense contractors, and telecoms to operate a compliant, low-latency AWS-compatible cloud behind their own firewall — a strategy that attracted notable co-investors. Confirmed investors included Battery Ventures, Bessemer Venture Partners, Intel Capital, SanDisk, and Qualcomm Ventures. By its Series C in 2016, Stratoscale had raised a total of $70 million, per public Crunchbase records, to compete directly with Nutanix and SimpliVity on hyperconverged infrastructure while adding the API-compatibility layer that they lacked. Stratoscale operated dual headquarters in Sunnyvale, California, and Herzliya, Israel, with a team that peaked at approximately 100 employees, per LinkedIn aggregate data. The company secured over 25 enterprise design partners, including a large US financial institution that contributed to an open-source Kubernetes-as-a-Service project called Merkury. In November 2019, following a period of strategic repositioning toward AI-driven operations, Stratoscale was acquired by a subsidiary of QCT (Quanta Cloud Technology), the data-center hardware division of Taiwan's Quanta Computer. The acquisition was publicly reported by Israeli business daily Calcalist, which noted that Stratoscale's technology would accelerate QCT's push into composable, software-defined data center solutions. What distinguished Stratoscale from other hyperconverged plays was its foundational bet on API fidelity rather than proprietary management layers. Unlike Nutanix, which offered its own hypervisor and management UI, Stratoscale sold a headless AWS region. Customers didn't adopt a new platform — they adopted the control plane they already knew. This AWS-before-AWS-Outposts architecture made the company an acquisition target for server manufacturers needing a software layer to compete with Dell's VMware integration.
